Efficient and high-performance LED response effects, such as blinking, breathing, and chasing, are critical to improving end-user experience in many human machine interface (HMI) applications.

The LP503x device is a 30- or 36-channel constant-current-sink LED driver. The LP503x has a 29 kHz, 12-Bit PWM generator for each channel, as well as channel/module independent color mixing and intensity control, formerly called brightness control registers to enable vivid LED effects with zero audible noise. Users can benefit from the device’s ultra-low shutdown Iq Power Saving Mode, while designers will appreciate the incredibly straightforward software coding of the LP503x’s three programmable R G B banks.

The LP503x device controls each LED output with a 12-bit PWM resolution at 29-kHz switching frequency. This control helps get an intensity that decreases smoothly and stops audible noise. Having different color-mixing and intensity-control registers makes writing the software code straightforward. When targeting fade-in, fade-out type breathing effects, the global R, G, B bank control reduces the microcontroller loading significantly. The LP503x device also implements a PWM phase-shifting function to help reduce the input power budget when LEDs turn on simultaneously.

The LP503x device has an automatic power-saving mode to get the ultra-low quiescent current. When channels are all off for 30 ms, the device total power consumption is down to 10 µA, making the LP503x device a possible alternative for battery-powered end equipment.
